Over millions of years, these objects grew larger, sweeping up material in their orbits and becoming the planets we know today. This model of solar system formation is known as the nebular hypothesis.

The Colorado Scale Model Solar System depicts the Sun, the planets, and the distances between them all on the same scale of 1 to 10 billion. That is, the real objects and distances are 10 billion ...
